   4 Subject: [PATCH 2/2] dsa: register every port with of_platform
   5
   6 The declaration of a different mac-addr using the nvmem framework is
   7 currently broken. The dsa code use the generic of_get_mac_address where
   8 the nvmem function require the device node to be registred in the
   9 of_platform to be found by of_find_device_by_node. Register every port
  10 in the of_platform so they can corrently found and a custom mac-addr can
  11 correctly be declared using a nvmem-cell declared in the dts.
